Master to Detail Records - Quicker way to do this?

Thanks Dan.  It is the item 3 that describes my situation.   I have a template project and therein I have created 7 tasks in a related child table and I have established an import button.  But from reporting point of view, we would like to set up all tasks in one hit.  I hope this answers your query. 

Thanks Mark. Pregnant records would be a great idea. But in my case all parent records are already there so retrospectively working on records may be a challenge.
